# Deploy and Host Evolution API on Railway

Evolution API is a free, open-source WhatsApp automation gateway that connects your WhatsApp number to a REST API. It lets you send and receive WhatsApp messages programmatically with no per-message fees and no Meta Business verification required.

## About Hosting Evolution API

Hosting Evolution API on Railway gives you a persistent, always-on WhatsApp API server with a public URL. Once deployed, you connect your WhatsApp number by scanning a QR code through the built-in manager dashboard. The server maintains a live WhatsApp Web session and exposes a REST API that your automation tools — like n8n — can call to send messages, receive replies via webhooks, and manage multiple WhatsApp instances. Railway handles the infrastructure so you never touch server config.

## Common Use Cases

- Sending automated WhatsApp appointment confirmations and reminders from n8n workflows
- Receiving inbound WhatsApp replies and routing them into automation pipelines
- Running a WhatsApp-based AI receptionist for clinics, salons, or service businesses

## Dependencies for Evolution API Hosting

- A WhatsApp number (personal or business) to scan the QR code
- An n8n instance or any HTTP client to call the REST API
- The `n8n-nodes-evolution-api` community node if using n8n

### Deployment Dependencies

- [Evolution API GitHub](https://github.com/EvolutionAPI/evolution-api)
- [Evolution API Docs](https://doc.evolution-api.com)
- [n8n Community Node](https://www.npmjs.com/package/n8n-nodes-evolution-api)

### Implementation Details

Set this environment variable before deploying:

```
AUTHENTICATION_API_KEY=your_secret_key_here
```

After deploy, open `YOUR_RAILWAY_URL/manager` → Create Instance → Connect → scan QR with WhatsApp.
